The system correcting the vibration of front axle assy comprises at least for manipulating the control convenience of the first dent removal equipment and the second dent removal equipment.According to this embodiment, control convenience is the control setup CTL of maneuvering system, and except calculating the function of the torque settings value of combustion engine MTH and MEL, the rotating speed that this control setup also comprises front axle assy corrects function.The correction torque that this correction function calculating will be applied by dent removal equipment.In this embodiment, these dent removal equipments are similarly the equipment driving front axle assy, and the rotating speed of front axle assy is controlled by control setup CTL, is namely controlled by combustion engine MTH and the second motor M EL.Therefore the first dent removal equipment is combustion engine MTH, and the second dent removal equipment is the second motor M EL.Because motor M EL is connected with front axle assy by drive belt with combustion engine MTH, the vehicle condition that motor M EL and combustion engine can participate in front axle assy is corrected.
And according to the present invention, vehicle condition correction function comprises to be selected to be responsible for providing to vehicle bridge correcting torque with the function of the dent removal equipment of less vibration.More properly, according to vehicle status data, control setup CTL selects combustion engine MTH or motor M EL, to transmit the correction torque anti-phase with the vibration of front axle assy.
Therefore control setup CTL calculates the correction torque that will be applied by the first dent removal equipment MTH or the second dent removal equipment MEL according to selection result.According to a kind of modification, control setup calculates one of them or the actv. correction torque separately of another dent removal equipment, to implement calibration phase.
According to the hardware configuration of maneuvering system, the computing machine for formulating these functions can concentrate on the position of monitor or be distributed in the equipment position that will control, thus scattered electrons controls equipment.And equipment can implement function calculating own, and the computing machine of dispersion is by such as CAN (English is " Controler Area Network ") bus-type or FlexRay
tMthe data communication bus of bus-type intercoms mutually and communicates with monitor.
And the computer location place in combustion engine MTH, vehicle condition is corrected function and be can be positioned on control setup CTL position, can send data after this computing machine to motor M EL or at the computing machine place of motor M EL.Each being equipped with in these computing machines can receive needs for calculating the communication facilities of the data of vehicle condition correction.
Therefore the invention still further relates to a kind of method correcting the vibration of front axle assy.Said method comprising the steps of:
The detecting step of the speed oscillation of-detection vehicle bridge TRAV,
-between combustion engine MTH and motor M EL, the selection step of dent removal equipment is selected according at least one vehicle status data,
-calculation procedure, described calculation procedure comprises and calculates and will be applied to correction torque in vehicle bridge by the dent removal equipment selected,
-start the setting up procedure being applied to the calibration phase in vehicle bridge according to calculated correction torque by described selected dent removal equipment.
Preferably, during calibration phase, control setup starts same dent removal equipment, corrects to keep best vibration.For this reason, once vibration be detected, before calibration phase starts, implement the selection of combustion engine MTH or motor.
Fig. 2 is the figure comprising curve 1, and this curve represents the rotating speed of front axle assy.Abscissa representing time data, and ordinate represents the rotating speed of front axle assy.Under this research conditions, curve 1 shows speed oscillation.The computing value that curve 2 and curve 3 represent the torque correction applied by motor M EL respectively and the computing value of torque correction applied by combustion engine MTH.Axis of ordinate representation unit is the torque value of Nm.The correction applied by motor M EL can increase anti-phase torque for each oscillation peak, and combustion engine MTH only can increase negative anti-phase torque.The reason of this restriction is, combustion engine is preferably controlled in recurrent state and can not reoffers positive torque when combustion engine is in best predicted point.Therefore, calibrating method will preferably select motor M EL to correct vibration.In fact, motor is reversible, and therefore motor can increase or remove torque, contrary with combustion engine when combustion engine is controlled in recurrent state.Combustion engine is remained on recurrent state can optimize consumption and protect component, such as catalyst.And, due to when motor is selected in 10ms by of short duration manipulation, and combustion engine is manipulated on high point (point moteurhaut), and the vehicle condition that motor performs is corrected can react faster on slow speed of revolution.Therefore according to used type of internal combustion engine, there is reactivity gain.
But, such as, when the charged level of the accumulator SOC for feeding electric motors is not enough, motor M EL can not be selected always.
Therefore, method according to the present invention comprises and depends on that vehicle status data selects the scheme of dent removal equipment.
Fig. 3 shows the diagram of circuit selecting the scheme example of dent removal equipment between combustion engine MTH and motor M EL implemented by CTL control setup.
In the step 10 of selection course, the checking of the data of control setup CTL Executive Agent state, wherein requires to optimize vehicle consumption, such as, points out that vehicle is in the data providing and consume preferential automatic running pattern.If the result is affirmative, motor is so selected to perform torque correction.In step 20, select motor M EL and calculate the correction torque that will be applied by motor.If the result is negative, so in a step 11, second data of control setup to the saturation conditions representing combustion engine MTH carry out the second checking.If saturated, positive torque can not be provided, therefore not process some speed oscillation peak values.Therefore, if this result is affirmative, namely combustion engine is saturated, and control setup selects motor M EL to perform torque correction in step 21.If this result is negative, implement in step 22 to consider that the calculation procedure of various data is to select motor M EL or combustion engine MTH.These data can be vehicle bridge rotating speed, the converter speed ratio of change speed gear box, saturation grade.
Increase such as to the checking of the charged level of accumulator SOC in these verification steps, to guarantee that motor M EL can provide torque.In addition, can preferably use combustion engine MTH as having high-revolving dent removal equipment in other cases, corresponding to the of short duration manipulation of motor M EL, it is synchronous higher than synchronous reaction during 10ms that combustion engine height is put.
The present invention can be applicable to all types vehicle being provided with hybrid power system.The vehicle bridge of at least two the vehicle bridge motor devices be provided with as vibration dent removal equipment is can be applicable to according to corrective system of the present invention and method.
